A mountain bike drivetrain consists of lots of moving parts, and could be considered to be the most important part on a mountain bike. There are bearings in the bottom bracket, moving parts with the rear derailleur, chains specific to how many speeds are on the bike, gear range, and chain retention systems like chainguides. All of these come into play for a mountain bike drivetrain and if one doesn't work right there might be an issue.
